Seven Deadly Skin Sins

Want gorgeous skin? Start by making sure you don't commit any of these skin-damaging crimes

Thou shalt not: stress "When your body is stressed, it pours out a stress hormone called cortisol," says Bank. This causes a multitude of things. "It robs the skin of its blood supply and can elevate blood sugar, which can cause cells to function abnormally," says Bank. It can also affect acne oil glands. So bottom line, when you stress out your skin may be more prone to breakouts and is likely to look dull and sallow. Bank recommends finding a stress-reducing activity that works for you. Whether you choose deep breathing, yoga, walking, "even 15 minutes can make a difference," says Bank.
